A private bathroom carved from the room you have

Adding an en-suite to a Holland Park bedroom is mostly an exercise in drainage and space. The new bathroom has to find a few square metres — from the bedroom, a landing or a cupboard — and then connect to a soil stack that may be some distance away, all within the depth of a period floor.

Waterproofing is the other non-negotiable. A bathroom built over a period timber floor must be properly tanked and detailed so it never leaks into the room below, and pipework has to be routed without butchering joists. These are the details that separate an en-suite that lasts from one that causes problems.

We plan the en-suite to take the least space for the most function, resolve the drainage and waterproofing properly, and fit it out — tiling, screens, heating, ventilation — in one contract, to the standard the rest of the house deserves.

What shapes a Holland Park en-suite installation

An en-suite succeeds on the things you cannot see — drainage routing and waterproofing.

01

Finding the space

A few square metres from the bedroom, landing or cupboard — planned to feel generous, not squeezed.

02

Drainage routing

Connecting to the soil stack within a period floor, without cutting joists badly — or a pumped solution.

03

Waterproofing

Proper tanking over timber floors so the room below stays dry, permanently.

04

Ventilation

Extraction designed in, because an en-suite is usually an internal room with no window.

Questions clients ask before they start

Where does the space for an en-suite come from?

Usually a corner of the bedroom, a landing or a cupboard. We plan it to take the least space while still feeling like a proper bathroom.

How is drainage handled in a period house?

We route waste to the soil stack within the floor where possible, without badly cutting joists, or use a concealed pump where gravity cannot reach.

Will it leak into the room below?

Not when it is properly tanked and detailed. Waterproofing over a timber floor is the single most important part of the job, and we do it correctly.

Does an en-suite need planning permission?

Internal en-suites are generally a Building Control matter, not planning — unless the house is listed, where listed building consent may apply.

What does an en-suite cost?

It depends on drainage, waterproofing and finishes. We give an honest budget band in pounds sterling (GBP) after a survey.
